Specification of Letters Patent.

Application filed July 5, 1919. Serial No; 2,08,?67.

accompanying drawings, forming a part of this specification. Myinvention relates to draft yokes for railway car fdraft rigging. I

One of the objects of my invention is to provide a draft yoke of simpleconstruction in which provision is made for the lateral swinging of thedraw bar. Other objects will appear from the description hereinafterfollowing.

In the drawings forming a part of this specification, Figure 1 is a sideelevation, part in vertical section, of a draft yoke embodying myinvention. Fig. 2 is a plan view of the forward portion of said yoke.Fig. 3 is a cross section taken on line 3-3 of Fig. 1.

Referring to the drawings, the numeral 10 indicates a yoke strap ofgeneral U-shape, provided at its free ends, and preferably upon theinner faces thereof, with laterally extended preferably arcuate tongues1212, which are adapted to enter similarly conformed grooves 1313interiorly provided in the side walls 14 of a yoke head 15. The saidyokehead is provided with a draw bar opening 16 to receive the draw bar17, and

is transversely slotted, as at 18, for the passage of the coupler key,by means of which the draw bar may be secured within the yoke head. Theupper and lower walls of the yoke head are provided with arcuateshoulders 19 against which the lugs inwardly extended/from the innerfaces of the U-shaped yoke strap are adapted to engage. The said lugsare referenced 20 and are preferably integral with the laterallyextended tongues 12. The yoke head is provided above and below withoutwardly ex.-

sides of the yoke strap 10.

tended walfs 21 on either-side of the arms of theyoke stra 10, whichwalls are rear- ,wardly outwar 1y flared, as indicated at 22, and alsoslightly outwardly flared forwardly, as indicated at 23, from a point,

as at 2 1, in Fig. 2 of the drawings, which is located substantiallyopposite the center ofpivoting between the yoke head and the yoke strap.In the construction described, it will be apparent that onlateralmovement of the draw bar the head of the yoke will pivot orswingabout the front end of the yoke strap as the center, the limit ofits pivoting action being fixed by the walls 22, when brought intoengagement with the On forward movement of the draw bar, the pull of theyoke head is against the lug 20 and on rearward movement of the draw barthe yoke head and the draw bar keyed thereto will slide rearwardly uponthe yoke strap. I claim:

1. In a draft yoke for railway cars, in

swinging head mounted between the free and the yoke head having upperand lower flaring shoulders adapted to engage the sides of the yokestrap to limit the swinging of the head upon the strap.

2. In a draft yoke for railway cars, in combination, a U-shaped yokestrap and a yoke head, the yoke strap being provided on its inner faceswith shoulders, the yoke head being provided with upper and lowershoulders engaging those upon the yoke strap, the sides of the strapbeing provided with laterally projecting tongues, the yoke head havinggrooves to receive said tongues and the yoke head being further providedwith shoulders having a forward and a rearward flare to limit theswinging movement of the yoke head upon the yoke strap.

In witness that I claim the foregoing I have hereunto subscribed my'name this 16th
